TL;DR
Amazon said AWS revenue rose 39% to $46 billion in the third quarter, its fastest growth rate since late 2021, while its contracted future revenue reached $578 billion. The cloud expansion is being funded by heavy investment: Amazon spent $75.9 billion on capital projects in the quarter and reported negative trailing 12-month free cash flow of $42.4 billion.
Amazon Web Services revenue rose 39% to $46 billion in the third quarter, its fastest growth since late 2021, as Amazon sharply expanded spending on cloud and artificial-intelligence infrastructure. The company spent $75.9 billion on capital projects during the quarter, while trailing 12-month free cash flow fell to negative $42.4 billion; Amazon shares declined more than 6% in after-hours trading following the results.
AWS operating income increased 55% to $17.8 billion, according to Amazon’s October 29 results. The company said AWS growth accelerated for a sixth consecutive quarter, from 17% in the second quarter of 2025 to 39% in the latest quarter, excluding currency effects. Chief Executive Andy Jassy said AWS’s contracted future revenue, or order book, reached $578 billion, up from $496 billion three months earlier.
Chief Financial Officer Brian Olsavsky said the quarter’s capital spending primarily related to AWS and AI. Jassy said most of Amazon’s roughly $220 billion capital-spending plan for 2026 would go to AWS, and that the company expects to spend “meaningfully more” in 2027. Amazon had raised its 2026 plan from about $200 billion in July, citing higher memory prices, CNBC reported.
The results also showed pressure on cash generation. Amazon reported negative $42.4 billion in free cash flow over the 12 months ending September, compared with positive $14.8 billion a year earlier. Operating cash flow over that period was $168.3 billion, while capital spending was $210.7 billion. Amazon’s long-term debt rose from $65.6 billion at the end of 2025 to $173.1 billion at the end of September. Separately, earnings per share of $1.89 fell short of the $1.96 analysts expected, and the company’s holiday-quarter revenue outlook was slightly below expectations, according to CNBC’s reporting of analyst estimates.

AI Infrastructure Meets a Cash Squeeze
The figures set up a central trade-off for Amazon: accelerating cloud demand is giving the company a reason to build quickly, but facilities, chips and power infrastructure require large upfront payments. Customers generally generate revenue as capacity comes online and is used, while construction and equipment costs arrive earlier. That timing gap helps explain how AWS can post rapid growth and rising operating income while Amazon’s overall free cash flow turns negative.
For investors, the issue is whether future cloud revenue and earnings will justify today’s build-out. The $578 billion order book indicates substantial contracted demand, but it is future revenue, not cash already collected or profit already earned. The after-hours share decline followed the spending and cash-flow figures as well as results that missed some expectations, including earnings per share and advertising revenue. The available source material does not establish one single cause for the market reaction.
Cloud customers may also feel the effects through the availability and pricing of computing capacity. The source report says large blocks of AI capacity are being reserved well in advance and that short-term access to older AI chips is selling at a premium. If supply remains tight, businesses planning AI projects may need to secure capacity earlier or weigh alternative chips and providers. Amazon’s spending pace also matters to competitors, which face pressure to add infrastructure as demand for AI computing grows.

How Amazon’s Build-Out Expanded
Amazon’s capital program has grown alongside AWS’s recent acceleration. The company said it expected about $200 billion in capital spending for 2026 in February, then raised that outlook to roughly $220 billion in July. Its third-quarter cash capital spending reached $75.9 billion. Amazon’s property and equipment grew from $357 billion at the end of 2025 to $508.9 billion at the end of September, a rise of about $152 billion over nine months.
The investment includes data centers, servers, networking equipment and Amazon-designed chips. Jassy said the company installs an AI accelerator about every 14 seconds. Amazon’s Trainium chips are used for some AI workloads on AWS, including much of the activity on Bedrock, the company’s model-hosting service, according to the source report. Amazon also says customers saved more than $2 billion during the quarter by using its own chips; that is a company-reported estimate, not an independently verified measure in the supplied material.
The cash figures reflect a longer spending cycle, not just one quarter. Over the 12 months to September, operating cash flow rose 29% to $168.3 billion, while capital spending climbed 82% to $210.7 billion. Equipment costs also appear over time: Amazon reported depreciation and amortization of $20.9 billion in the quarter, up 25% year over year. The company has also announced a $1 billion “Built Together” commitment for communities near its U.S. data centers, including energy and water-efficiency upgrades.
“The majority of the roughly $220 billion planned for 2026 goes to AWS.”
— Andy Jassy, Amazon chief executive
Returns and Capacity Remain Unclear
Amazon has not provided a specific 2027 capital-spending figure, a timetable for the infrastructure build-out to generate returns, or a breakdown of how much of the quarter’s spending went to data centers, chips, power and other equipment. It also has not said how much its AWS order book will convert into revenue in each coming quarter. Contracted future revenue offers a measure of demand, but does not by itself establish when customers will use the capacity or how profitable those contracts will be.
The source material does not quantify the share of Amazon’s spending financed by new borrowing, nor does it establish how long negative free cash flow may continue. Jassy argued that owning or securing infrastructure can be more profitable than renting capacity from specialist providers, but his comparison was a management claim, not an audited industry-wide measure. The effects of component costs, including memory prices, and access to power also remain difficult to separate from the wider investment total.
Watch Spending and AWS Demand
Investors and customers will look for Amazon’s next quarterly results and any updated guidance on capital spending, free cash flow and AWS growth. The company’s holiday-quarter revenue forecast is another near-term measure, given that its outlook came in slightly below analyst expectations. Amazon has said it plans about $220 billion in capital spending for 2026 and expects a higher amount in 2027, but the timing and scale of that increase will depend on the company’s subsequent disclosures.
Customers will also be watching whether new AI capacity becomes available on the timetable they need and how pricing develops for scarce computing resources. Amazon has said it plans to sell its Trainium chips outside AWS beginning in late 2027. That is a future product plan, not a current source of revenue. Until the company reports more detail, the key questions are how quickly infrastructure investment turns into billable usage and whether AWS growth can support the cash demands of the build-out.
Key Questions
How fast did AWS grow in the third quarter?
AWS revenue increased 39% year over year to $46 billion in the July-to-September quarter, Amazon reported. The company described it as the fastest growth since the end of 2021.
Why was Amazon’s free cash flow negative?
Amazon’s trailing 12-month capital spending reached $210.7 billion, above operating cash flow of $168.3 billion. The resulting reported free cash flow for the 12 months ending in September was negative $42.4 billion.
What is AWS’s $578 billion order book?
It is the amount of contracted future revenue AWS had, according to CEO Andy Jassy. He said it rose from $496 billion three months earlier; it is not revenue already collected.
How much does Amazon plan to spend on capital projects?
Amazon expects to spend about $220 billion in 2026, with most of that amount going to AWS, Jassy said. He also said 2027 spending would be “meaningfully more,” without giving a specific figure.
What remains uncertain about the AI investment?
Amazon has not disclosed a detailed spending breakdown, a specific 2027 budget or a timetable for when the new capacity will generate returns. It is also unclear how quickly the order book will convert into revenue and whether current capacity constraints will ease.
